Wow what a day; I have a pair of B5-Lite radios in service for a event inwhich my company is sponsoring the Wifi access for here in Las Vegas… and boy did these radio get hot today!
The spec sheet says Operating Temperature is -40°C to +55°C (-40°F to 131°F) well lets just say that on top of a Las Vegas Hotel with a rubber/tar roof we hit a astonishing 203°F exceeding the spec sheet rating by 72°F which in my opinion is insane!
Now granted these units did continue to function at a higher error rate / lower bandwidth rate but compared to other radio manufacturers like E-Band, Radwin & Siklu radios failed miserably!
My Siklu units operate at higher / hardened temperatures here in desert but by design there entire back is a heat sink to help with heat distribution away from critical chips / components.
Mimosa’s R&D team is going to have to rethink the design of these units and all future units so they don’t get ruled out or passed up for consideration by a whole region of wireless IT Professionals.
I know when I shop around for outdoor IT equipment I always buy the units that by design can operate in higher environment and are hardened! But as far as these units are concerned I just wanted to try them out despite there “low” high temp rating.
After this 4 day event is over I am going to have to reconsider whether these units should be marked as lab / test equipment or if they can be put into production use after exceed the max rating for 4+ consecutive days.
I have attached the 24 hour graph showing the high temperatures.
If anyone has any opinions or suggestion please let me know.
